I buy a 10 lb bag for 75$ thats 50 cents a serving (1/3cup servings.) The only thing that compares cost wise to that is 4oz can of tuna, everything else chicken, tuna, beef is much more expensive per serving, or per ~20ish grams of protein.

Also post workout whey is almost your only option. Bloodflow is still dominated by your muscles post-workout and you only have a 2 hour window to maximize your recovery, this is why bodybuilders reach for whey protein, because it is "pre-digested" and can be absorbed rapidly. Also for post workout meals don't eat any fat, it slows digestion. Then you should eat a full meal 1-2 hours after your post workout meal, this one being all real food.
